Windows 7: BSODs occuring randomly and increasingly more frequent.

BSODs occuring randomly and increasingly more frequent.

I am an 80 yr old computer duffer and have been experiencing an increasing number of BSODs that just seem to occur randomly.
All my drivers I believe have been checked and updated, have run Memory diagnostics, used system restore and system reinstall but nothing seems to get to the root of the problem(s)

Am enclosing Windows_NT6_BSOD_jcgriff2 folder & the PERFMON HTML file along with my system info as spelled out in the BSOD Posting instructions all in a BSOD.rar file.

Would appreciate any help.
Thanks dlddemon

Before we can even begin to investigate you need to update or remove this driver. USBNUMP.sys. Yours is from 2002 (windows ME era) and it cant possibly work in win 7.

I would also run a malwarebytes scan just to be sure

Please download the free version of Malwarebytes.
Update it immediately.
Do a full system scan
Let us know the results at the end.

Thanks zigzag3143 for your quick response .
Ran Full system scan using Malwarebytes results, the scan completed successfully. No malicious items were detected.
I tried to update the driver but could not find any update so saved a copy of the file and deleted USBNUMP.sys from windows/system32/drivers.

I then started to make a note to myself about what had been done and found that my keyboard would not function using Notepad, Wordpad or Outlook While going back and forth trying to type a message I got another BSOD error, DRIVER IRQL NOT LESS OR EQUAL.

I restarted the computer and tried once again to type a message but was unable to do so.
I then reinstalled the saved USBNUMP.sys driver and again restarted my computer.
I was then able to use the keyboard as usual.

So I am now back to where I started at the beginning of this exercise.

NOTE: while searching on the net for an updated driver I found that this driver had been used by IBM for their numerical keyboard, could this be why I experienced a keyboard malfunction?

Where do I go from here?

Good news bad news I guess. No malware, but that USB driver cant be needed. It is far older than the system you have. Might want to investigate where it came from and when

OK. I rolled back the USBNUMP.sys driver to Generic HID Keybaord now the keyboard is working fine and the USB driver for Lennova keyboard is no longer shown.
I am now ready to move on, what's next?

Hello zigzag 3143.
The BSODs are back. I am attaching New folder RAR of the minidumps for the past 3 days anything prior to that will be in my original post. Is there anything else I can provide?

The USB driver is still in the mix USBNUMP.sys. You also have a 2007 BIOS thats need updating.

I thought that by rolling back the driver that I would be deleting the driver but obviously not so. I have now deleted the USBNUMP.sys.

As for the BIOS, I have not been able to update it using the usual WinFlash method. I will try again and advise.
